Drugs used in chemotherapy, such as FAU, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. This phase I trial is studying the side effects and best dose of FAU in treating patients with advanced solid tumors or lymphoma.

Maximum tolerated dose, defined as the dose at which no more than 1/6 patients develops dose-limiting toxicity, graded by NCI CTCAE version 4.0 [ Time Frame: Up to 28 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Clinical response to FAU, evaluated using the new international criteria proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee [ Time Frame: Up to 30 days ] [ Designated as safety issue: No ]

Response will be described by point estimates and exact confidence intervals.

Pharmacokinetics of FAU, including Cmax, Tmax, AUC 0-last, AUC 0-infinity, CL, t1/2, and Vss [ Time Frame: Days 1 and 22 of course 1 at pre-treatment; at the end of infusion; and following the end of infusion at 15 and 30 minutes and 1, 2, 4, 8, and 24 hours ] [ Designated as safety issue: No ]

All pharmacokinetic parameters will be summarized with standard descriptive statistics.

I. To assess the safety and tolerability of FAU in patients with advanced solid tumors or lymphoma.

II. To determine the dose-limiting toxicity and maximum tolerated dose (MTD) of FAU in these patients.

SECONDARY OBJECTIVES:

I. To observe the clinical response in patients treated with FAU. II. To characterize the pharmacokinetics of FAU in these patients. III. To explore whether an association exists between pre-treatment 18F-FAU PET standardized uptake value levels and time to tumor progression after treatment with unlabeled FAU.

IV. To estimate the protein levels of thymidylate synthase (TS) in archival tumor tissue samples and to compare them with thymidine kinase (TK) and TS protein levels and TK and TS mRNA levels in fresh tumor tissue samples from patients treated at the MTD.

V. To explore the relationship between genetic polymorphisms of TS and tumor 18F-FAU uptake.

OUTLINE: This is a multicenter study.

Patients receive FAU IV over 1 hour on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
